This blog is updated daily.
A general description is here.
‘available.packages()’ and hence ‘install.packages()’ now pass their ‘...’ to ‘download.file()’, fulfilling the wish of PR#17532.
The use of a character vector with ‘.Fortran()’ is formally deprecated and gives a non-portability warning. (It has long been strongly discouraged in ‘Writing R Extensions’.)
print()ing and auto-printing no longer differs for ‘function’s with a user defined ‘print.function’, thanks to Bill Dunlap's report.
